Note that I specifically said that the tests I had run were done in the same room as the stereo system, usually 6-8 feet away, NOT several rooms away.
These tests happened about 5 years ago when I took my SB3 over to a friends house to show it off, how nice it was to use and how good the sound was from such an inexpensive box, and that it could work well with his expensive DAC. I was running this off my laptop with the server on the laptop and using the web interface to control things. After listening for a while he said that he could hear a change in the sound when I was actively doing things with the computer (searching for the next song to play etc). Well that surprised me I had never heard that before. We then started doing some tests to see if it was related to the fact that it was the computer with the server or if it was just the laptop in general. We loaded the server on his Mac mini and sure enough, working with my laptop caused a change in the sound, even if it had nothing to do with the sound flow (server on another computer, playback from SB3). We tried this with one of his laptops and got similar results. Doing things with the Mac mini didn't cause any change, but it was not in the room with the stereo. This got me thinking about how computers can affect things. I started running tests in my system, and other peoples systems. We did find that there was significant difference in sensitivities, some systems more than others. At this point I was not interested in a more rigorous testing to try and figure out correlations (what was it about a system that made it more sensitive). The thing about the mouse was not a wireless mouse, just the increase in activity in the computer when moving the mouse. Interestingly the couple places I have heard this have NOT been on "audiophile" systems, but at peoples houses with "normal" systems. I was at one ladies house, she had the stereo on but the song had stopped playing, she was working at her laptop, we could definitely hear a grinding sound coming from the speakers, changing in concert with the movements of the mouse. I have heard something similar to this at another friend's house, again not an audiophile system. Since this has little to do with the thread topic I'll shut up now.
